 Small change, changed back last line of `is_main_site` to the following.

 {{{#!php
 return (int) $site_id === (int) get_network( $network_id )->site_id;
 }}}

 Because there is a magic getting in WP_Network, calling site_id will call
 `get_main_site_id`. The reason you want to make sure the magic getter run,
 is that it only runs once. This stops the logic running multiple times.
